9 Claims.

This invention relates to replacement window shade structures and thelike.

An object of the invention is to provide for a high degree of facilityin attaching window shades to shade rollers of the spring wound type,either in the replacement or the initial application of the shade web toa roller.

Another object of the invention is to provide means for proper andaccurate application of a shade web to a roller, Without the need forcomplicated and expensive factory operations, and with a substantialsaving of time, expense, and skilled labor costs; the same means beingof advantage in the replacement of window shade webs to existing rollersin the home.

Other objects of the invention are: to provide for reversal of a shadeweb upon a roller, to conceal soiled portions thereof; to provide anovel and useful replacement shade package wherein the shade isprotected against injury during handling and shipment; to provide meanswhereby a replacement shade may be applied to any proper availableroller without having to unroll the shade prior to hanging thereof; andto bviate all possibility of an unsatisfactory home application ofreplacement shades to used rollers.

These and other objects are attained by the means described herein anddisclosed in the accompanying drawing, in which:

The history of the art to which this invention relates indicates thatsome satisfactory method of rendering window shades replaceable uponshade rollers, has long been sought. It has been proposed, for example,to apply tubes or cylinders of cardboard, metal and the like, to theupper end of a replacement shade for fa- LLI cilitating applicationthereof to existing rollers. There has been no evidence, however, of anynoticeable commercial success in connection with those proposals, thefailure of which is believed to be attributable to excessive costs andto the difficulty of maintaining a fixed relationship of the shade webto the roller. Some of the prior methods also failed due to the factthat the practice thereof required a degree of skill not ordinarilypossessed by the purchasing public, in the matter of applying thereplacement shade. One of the primary objects of the present inventionis to avoid all necessity for extraordinary skill or care in theapplication of replacement shades to existing rollers, and to sosimplify the structure that the cost thereof will be within reach of thepublic generally,

With reference to the accompanying drawing, and especially to Fig, 2,the replacement shade of the invention is seen to comprise a singlethickness of shade material I2, which may be of paper, fabric, or othersuitable material properly coated or otherwise treated to impart theretothe necessary characteristics expected in a window shade or the like. Atits upper end, the web I 2 is turned upon itself to form a hem orcylindrical loop l3 of the proper size for reception of standard shaderollers. Since standard shade rollers vary to some extent in diameter,the hem or loop is made sufliciently large to accommodate the largest ofthe ordinary size of standard rollers. Where the free upper edge M ofthe web is fastened upon itself, resort may be had to stitching I5 orany other acceptable means of fastening, such as an adhesive or clips orclamps of one kind or another.

In the embodiment illustrated by Fig. 2, a portion of the inner face I5of the hem may carry a narrow longitudinal adhesive coating or strip H,which by preference extends from one side edge of the shade web to theother. The adhesive coating preferably is one which is soluble in wateror other liquid. To insert a roller into the hem or tubular portion l3,and to produce the necessary connection or fastening of the web to theroller, it is necessary only to moisten the roller prior to inserting itinto the hem, thereby rendering the adhesive tacky and causing a bondwith the surface of the roller. As will be understood, the setting ofthe adhesive will result in a substantial fixation of the roller withinthe hem or tubular portion l3 of the replacement shade.

At the lower end of web l2, the free edge I8 is turned upwardly andfastened by means of a line of stitching H! or its equivalent, tofurnish a second loop or hem 23 adapted for reception of the customaryreinforcing bar 2|. The hem or loop 20 may be dimensioned to snuglyreceive the reinforcing bar, if desired, but in the form of theinvention disclosed said hem is made sufficiently large to accommodate astandard shade roller in a manner similar to the hem or loop l3 at theupper end of the shade. The purpose of this is to enable the user toreverse the shade, that is, to suspend it from either one of its ends,so as to conceal as much as possible any soiled areas of the shadematerial.

The illustration of Fig. 1 shows how the replacement shade of Fig. 2 maybe spirally rolled into package formation for protecting the shadeduring handling and shipment, at little expense and with the advantageof great convenience. It will be noted that in the package form, theshade is Wound with the hem or loop l3 disposed exteriorly, and with thereinforcing bar 2| transferred to the web or loop that would customarilyreceive the roller. Thus, the hem or loop 20 is disposed interiorly ofthe package, and does not, in the package formation of the shade,support the reinforcing bar. Accordingly, the application of the Fig. lshade to a roller requires merely the shifting of the reinforcing bar 2|to the interior hem or loop 20, and the insertion of a moistened shaderoller into the exterior hem or 100p IS without unwinding the packageprior to suspending the ends of the shade roller from the windowbrackets. The package of Fig. 1 may easily be wrapped with paper toprotect the shade from soil, while the exteriorly disposed reinforcingbar effectively prevents injurious bending or cracking of the shadematerial during handling and shipment. It is of great advantage to beable to apply the shade to a roller Without having to unroll the shadebefore suspending it from the window brackets.

In the modification of Fig. 3, the shade web I 2 has its upper loopedend 22 furnished with an adhesive coating 23 extending from the freeedge 24 of the web to a location 25 at one side of the hem, so that theadhesive coating may serve initially as a means of maintaining the loopformation, while at the same time functioning in the manner of thecoating ll of Fig. 2. In this case, the stitching may be dispensed with,if desired.

In the modification, Fig. 4, the line of stitching 26 maintains the loopformation; one or more tacks or other fasteners 21 are driven into theroller 28 for fixing the loop or hem to the roller, thereby dispensingwith the use of an adhesive entirely. In this view, the character 25indicates a pintle on one end of the shade roller, reinforced by an endflange 36), in accordance with customary practice. The pintle end flangeare shown also on Figs. 5, 6, and '7.

In a shade structure such as illustrated by Fig. 4, wherein the webcarries no adhesive coating, it may be desirable to employ a shaderoller such as is disclosed in Fig. '7, wherein a narrow longitudinalstrip 3! of adhesive is furnished upon the roller itself. As willreadily be evident, the roller of Fig. 7 may be inserted into a shadehem or loop of the Fig. 4 type, after first moistening the solubleadhesive area 31 of the roller, thereby rendering it unnecessary to usetacks or other fasteners 2'! for establishing a fixed relationship ofthe roller to the shade hem or loop.

With reference now to Fig. 5, the web l2 has its upper end turned uponitself, and secured by means of a line of stitching or the like 32 toprovide a hem or loop 33, in substantially the same manner as heretoforeexplained. Along the length of the hem or loop, a series of perforations34 are formed, so that a portion of the roller will be exposed after theroller has been inserted into the hem or loop. After insertion of theroller, an adhesive patch 35 is applied to the web. over and about eachof the apertures 3 1, so that the patch will stick to the surface of theroller Where it is exposed, while at the same time fastening itself tothe shade material along the margins of each aperture. Application ofthe patch as explained, will effectively anchor the shade material tothe roller, so that relative movement between the roller and the hemwill not occur. In the preferred form of this modification, theapertures 34 will be formed in the hem with the major axes thereofdisposed circumferentially about the roller, thereby to furnish thegreatest possible anchorage for the roller. At the extreme right of Fig.5, the aperture is disposed with its major axis extended lengthwise ofthe roller, so that this arrangement is possible also. When the shade ofFig. 5 is constructed of strong sheet material, the adhesive patch maybe of the kind wherein the adhesive element thereof is non-drying, andin that case it will be possible to repeatedly apply and remove theadhesive patches whenever it becomes necessary to launder the shadematerial. However, when the shade material is of inexpensive paper, itmay be preferable to apply less expensive adhesive patches formed fromgummed paper or the like. In either event, the structure shown in Fig. 5furnishes an ac curate, convenient and inexpensive way of applyingreplacement shades to existing rollers.

The structure of Fig. 6 is a variation of that disclosed in Fig. 5, butit includes the punching of apertures 36 in the material forming thehem, although in this variation a flap 31 is permitted to remain alongone longitudinal edge 38 of the aperture. The flap, after insertion ofthe roller into the hem, may be adhesively fixed to the area 39 of theroller where exposed through the hem aperture. The drawing figureindicates at 60 a suitable adhesive on the flap, to be pressed againstthe roller area 39 subsequently to positioning the roller within theweb. The adhesive coating may be applied to the web by the purchaser, orit may be applied at the shade factory in the form of a soluble gum orthe like, to be moistened by the purchaser at the time of placing theshade upon the roller.

In each of Figs. 5 and 6, the various apertures may be formed of anydesired contour, including circular and ovate shapes as well as angularshapes of various designs. In Fig. 6, as well as in Fig. 5, the adhesiveflap may be repeatedly applied to or removed from the roller providedthat the shade material is of such qua].- ity and character as towithstand the repeated manipulations. As in all other forms of theinvention, the rows of stitching indicated at 32 in Figs. 5 and 6 may bereplaced by suitable clips or clamps, or an adhesive connection.

It is important to note that the shade structures of Figs. 2, 3, and 6may be constructed of a material which is water pervious, especially atthe hem or loop, so that fixation of the shade to a roller may beachieved by first inserting the roller into the hem or loop, andthereafter applying Water or other solvent to the outer surface of thehem or loop material, the water or solvent thereby acting to penetratethe shade material for rendering the interiorly disposed adhesivesufliciently tacky to effect a bond with the roller. This is animprovement which greatly facilitates and simplifies the application ofa replacement shade to a shade roller.

In Fig. 7, the strip of adhesive indicated at 3| may be a paper ribboninitially carrying adhesive on both of its faces, and applied to theroll so as to expose one of the adhesive faces to the inside of the hemor loop portion of a shade.

What is claimed is:

1. A window shade structure comprising a shade roller, a singlethickness web of shade material having a pre-hemmed end in which theroller is inserted by moving it longitudinally through the hem, andfastening means cooperating with the roller and the hem portion of theshade for precluding rotation of the roller therein, said fasteningmeans comprising an adhesive rendered effective for so precludingrotation, only after insertion of the roller into the hem.

2. A replacement window shade, comprising a single thickness web ofshade material having an end for association with a shade roller, saidend being hemmed initially and dimensioned to receive a shade rollertherein, and a normally dry adhesive means associated with the hempermitting free insertion of the roller therein, said adhesive beingrendered tacky by moistening through the web subsequently to insertionof the roller into the hem.
